Was an email verification code would not accept it?

In regard to the 6-digit email verification code during the filing process:

When you go to get the code from  your email, you have to leave the screen open that asks for the code.  If you close the interface, the code will be seen as expired or not valid.   You have to use a different browser tab, or a different window, or a different browser, or your phone to check your email and get the code.  

If you're copying and pasting, it may include a space before or after. Make sure you are only pasting the numbers or removing the spaces after pasting.
